Komatsu pc50 bucket

[Fubar008]

I'm new to the excavator world and just bought up a komatsu pc50. I'm planning on using on my property for mostly clean up work. We live in 200 acres of woods so there's always down trees. I also need to do some ditch work on my Rd and would like a ditching bucket. I did some research and it seems tilt is worth the money. But I'm confused on size and compatibility with my machine. Any advice would be great, thanks

I think its 45mm pins and a 36" wide tilt bucket is a good size for that machine.

Welcome to, TBN !
You should probably be looking in the 36" range for a ditching bucket. Just remember that the hard and heavy work is for your regular tooth bucket and think of the ditching (often call grading or clean up) bucket for the above. One with the "wrist" is more versatile but much more expensive.
You do have a thumb right? If not this is the first accessory you need.

I do have a thumb. That was a must when I was searching as well as an enclosed cab (weather in VT is often cold). I did notice everyone seems to call the bucket different names . I assume you disconnect the thumb hydraulics for the tilt function? And it sounds like most machines in this size use 45mm pins?

They make a valve that has two ports need one each side that you can leave the thumb lines attached and just plug in the tilt bucket lines and turn the valve to work the other ports.

I'm not certain of the vocabulary concerning pins, I just bought a bigger excavator with a pin grabber for bucket change and am under the impression that the pin size refers/matters only for attachments that fit the pin grab. ?

These are 60mm pins but if you don't have the "grab" and are switching buckets the old way by pounding out the 2 pins that go through the stick and curl links.....
I'm learning too. I'm coming out of an excavator that I've owned for 22+ years and a couple of years older than that.

Just sold ole nelly last week.

we have 2 machines the same size one with pin grabber and one without all the buckets fit both machines.

So if you're setting up a machine and adding one of the many pin grabbers, you'd match the pins on the excavator?
I was thinking that they (pin grabbers) were standardized by pin size, a XXmm pin grab would work with any attachment with the same XXmm pins.... across all makes of attachments. But I've noticed that there's different "spread" in both between the pins and between the "ears".
Maybe it's like this now with every manufacturer having slightly different dimensions (other than the pin diameter)
with the idea of selling their buckets and attachments. This was the situation 20 years ago with skid loaders.
I am aware of some overlapping in these dimensions between manufacturers but it seems to be coincidental.

You’re pc50 bucket pin dimensions; 45mm pin diameter, 170mm width of ears (usually couple mm over stick width), 230mm pin center to center. Looks like komatsu uses these same dimensions for their 40 thru 55 machines. You’re correct pin grabber will have these mount dimensions and it will grab buckets with same dimensions.The hydraulic pin grabbers will also grab buckets with slightly shorter and longer pin centers than your standard.
Tilt ditching buckets are nice , I’ve got a 51” for my 6ton excavator. I’d say you’d do well with 36”-42” .
